Got my positive opk on April 19th and we BD 2 days before and 3 days after. My period has usually been coming a few days early for the past couple of months. I've been feeling like I'm going to start since last Thursday but nothing yet. I'm due tomorrow. Took 3 pregnancy test on 10, 11, and 12 dpo but all negative. Is there still a possibility? Is it normal to not get a bfp until after your period is due?
